Jordan, Fort Myers, Fla., assignors t0 Sentinel Frechek Locks, Incorporated, a corporation of Illinois Filed Mar. 3, 1964, Ser. No. 348,948 25 Claims. (Cl. 19474) The invention relates in general to coin operated locks and, more particularly, to a combined coin and key operated lock.

The coin and key operated lock of the invention may be used in many environments and one particular environment is in the use of storage lockers with the lock mounted in the door to cooperate with the door frame. The lock is normally unlocked, that is with the lock bolt retracted, and manipulating the key will not lock the mechanism until a coin is inserted. After locking, the key may be withdrawn to lock the storage locker and the coin is retained as a deposit for return of the key. Upon return, the user manipulates the lock with the key to open the storage locker whereupon he may recover his articles stored therein and may also recover his coin deposit. Thus, the lock mechanism is a coin return lock providing free service.

An object of the invention is to provide a coin operated lock which will refund the coin to the operator.

Another object of the invention is to provide a combined coin and key operated lock wherein a coin is required before the key may be fully manipulated and yet the coin is returned to the user.

Another object of the invention is to provide a simple and reliable combined coin and key operated lock having a minimum of parts and a maximum of reliability.

Another object of the invention is to provide a coin and key operated lock wherein the presence of a coin is required for actuation of the lock by the key and the coin is not recoverable until the lock mechanism has again been returned to its initial position.

Another object of the invention is to provide a coin operated lock wherein thrust through opposite faces of the coin is provided for actuating the lock mechanism.

Other objects and a fuller understanding of the invention may be had by referring to the following description and claims, taken in conjunction with the accompanying drawings, in which:

FIGURE 1 is a front elevational view, with the cover removed, of a lock embodying the invention;

FIGURE 2 is a view similar to FIGURE 1 and showing a coin in place and the lock in a position ready for actuation;

FIGURE 3 is a view similar to FIGURE 1 and showing the lock actuated;

FIGURE 7 is an enlarged partial view of the lock with no coin therein; and,

FIGURE 8 is a partial view similar to FIGURE 1 showing a modification,

FIGURES 1-7 show a lock mechanism 11 which is a preferred embodiment of the invention. The mechanism 11 is contained within a lock case 12 which may be mounted on a door 13 to cooperate with a door frame 14. The door 13 may be a door to a locker contained in the door frame 14. This may be a storage locker, for example, for storing articles therein.

3,233,713 Patented Feb. 8, 1966 The lock case 12 has a rear wall 17, a sloping bottom wall 18, a side wall 19 and mounting ears 20. The mounting cars 20 may be riveted to the inside of the door 13 as shown at 21 in FIGURE 4. A cover 22 covers the front of the lock case 12 and normally abuts the inside wall of the door 13. This cover is shown in FIGURE 4 but is shown removed in the remaining FIGURES 1-3 for clarity.

A lock bolt 25 is mounted in the lock case 12 for reciprocal movement between a retracted position shown in FIGURE 1 and an extended position shown in FIG- URE 3. In this extended position, it may extend into a locking aperture 26 in the door frame 14 or otherwise engage an abutment fixed to the door frame 14. The lock bolt 25 has a face wall 27 on an inner surface and has an inner extension 28 with an abutment 29 depending therefrom. A barrel 31 is fixed in the lock case 12 and, as shown, the barrel has rearward extensions 32 extending into a plate 33 fixed to the case 12. The front of the barrel is contained in an aperture in the cover 22 to retain the barrel 31 in place. A key cylinder 34 is journalled for rotation in the barrel 31 by a key 35. A lever as has a first leg 37 fixed to the rear of the key cylinder 34 to turn with this cylinder. In this embodiment the lever 36 has an arcuate movement of about degrees from a first arcuate position shown in FIGURE 1 to a second arcuate position shown in FIGURE 3. A second leg 38 is provided on the outer end of the first leg at right angles to this first leg 37. An extending tongue 39 is provided on the outer end of the second leg 33. A fixed abutment 41 is fixed on the case 12 by being fastened to the cover 22. This fixed abutment has a first surface perpendicular to a first path of reciprocation 42 of the lock bolt 25. The abutment 41 also has a short extension 43 near the bottom thereof and near the cover 22 at right angles to the first surface. A first coin chute 44 is defined by the fixed abutrnents 41 and 43 and the face wall 27 of the lock bolt 25. FIGURE 2 shows a coin 45 disposed in this first coin chute 44. A second coin receiving chute 46 is provided in the front cover 22 and the door is to permit insertion of the coin 45 into the first coin chute 44. A coin of the proper denomination is prevented from falling downwardly out of the first coin chute 44 by the extension 43 but smaller coins will fall through. The first coin chute 44 is aligned with the second coin chute upon the lock bolt 25 being in the retracted or first position of FIGURE 1 and being Inisaligned when the lock bolt 25 is in the extended or secend position shown in FIGURE 3.

An arcuate slot 48 is cut into the face wall 27 of the lock bolt 25 on an arc of movement of the lever second end 38. This lever second end 38 moves in an arcuate path which is a second path of movement 49 which intersects the first path 42 at an acute angle. This is better shown in FIGURE 7. The arcuate slot 48- may be considered an angled slot and may be formed with straight walls for ease of manufacture and disposed along a tangent to the arcuate path 49. This slot 49 has a bottom wall 50 and a re-entrant wall 51. I

A shelf abutment 54 is fixed on the wall of the case 12 below the face wall 27 of the lock bolt 25. A coin return receptacle 55 is connected to and made part of the case :12 below the shelf abutment 54. A coin opening 56 is provided in the rear wall -17 of the case 1 2 so that the opera-tors finger may be inserted to withdraw a coin resting on the sloping bottom wall 18. A coil spring 57 is connected between the lever 36 and a post 58 on the case 12 which is off center relative to the pivot axis of the key cylinder 34. Thus the spring 57 acts as a detent urging the lever 36 toward either the first or second arcuate position.

Operation The lock mechanism 11 has been shown as being a key and coin operated mechanism with a coin return provision. The lock mechanism 11 may thus be used in a locker tolock a door 13 to a frame 14. The lock mechanism may be mounted on the inside of the door 13 with only the face of the key cylinder 34, the key 35 and the coin slot 46 visible from the exterior of the locker. The environment shown is a parcel checking locker or similar use wherein a coin, for example a quarter, is required to actuate the lock to the locked position shown in FIG- URE 3 to lock the door 13 but the coin is returned when the key is reactuated to open the door 13. The key is captive in the key cylinder 34 when in the normal position shown in FIGURE 1. Thus the key cannot be removed from the. look without deposit of the required coin and also the key 35 may serve as a handle so that one may pull open the door 13. The operator may place the parcels to be checked within the locker and then reclose the door. When the coin is inserted through the second coin chute 46, then the key cylinder 34 may be turned to the position shown in FIGURE 3 which extends the lock bolt to lock the door. In this position, the key may be removed from the key cylinder so that the persons articles are securely locked in the locker.

If no coin is in the first coin chute 4 such as the condition shown in FIGURE 1, the key 35 is unable to actuate the lock. In this condition of absence of a coin, the lever second end 38 will pass completely through the first coin chute 44 into the arcuate slot 48. In this position, the surface 6t) of the lever second end 38 will strike the bottom wall of the slot 43. Continued urging of the lever 36 in a clockwise direction as viewed in FIGURES 1 and 7 will provide a component of force parallel to the first path 42 which will extend the lock bolt 2-5 very slightly toward the extended or second position shown in FIGURE 3. This extensile movement is very short and will terminate when the surface 61 engages the rc-entrant wall 51 of the arcuate slot 48. This engagement of these two surfaces and 6-1 with the slot walls 50 and 51 will provide a primary component of force from the lever 36 to the'lock bolt 25 which is essentially perpendicular to the first path 42. Further, the component of force from the lever 36 to the lock bolt 25 which is parallel to the first path 42 will be insufficient to move this lock bolt 25 outwardly. The re-entrant wall 51 effectively locks the lock bolt in a position essentially at the retracted position of FIGURE 1 and prevents extension of this look bolt 25. This is a safeguard mechanism to prevent anyone tampering with the lock such as trying to extend the lock bolt to the extended position by inserting the point of a knife through any crack between the door 13 and door frame 14 and digging the point of the knife into the lock bolt to try to extend it. Further, the detent spring 57 will retain the lock boltin the retracted position when in the position of FIGURE 1 despite such tampering activities.

If the corner 62 on the lever second end between the surfaces 60 and 51 is more rounded than the corner 63 between the slot walls 50 and 51, then this corner 62 will not engage the corner 63. In this case the lever 36 may only be rotated clockwise until surface 69 engages slot wall 50 and surface o1 engages slot wall 51. This will establish two engagements each at about a 45 degree angle relative to the horizontal, considering that the lock "-11 is presumed to be mounted vertically on the inside of a vertical door. Thus, the force from the lever 36 to the lock bolt 25 will be along two lines each at about a 45 degree angle on opposite sides of a vertical and thus the primary component of force will be vertically downward. This component of force is thus perpendicular to the horizontal first path 42 to prevent extension of the lock bolt 25. This will be true even though the lever 36 is not proportioned or positioned to strike the lock bolt 25 at a 45 degree angle. If the corner 63 is more rounded 4. than the corner 62 on the lever 36, then the lever 36 may the rotated clockwise to a position whereat the more pointed corner 62 strikes a generally horizontal portion of the rounded corner 6-3. In this case also, the primary component of force will be generally vertically downward and generally perpendicular to the first path 42 to preclude outward movement of the lock bolt 25. Since the lock bolt may not be extended :fu'lly without a coin in place, the key remains captive in the lock.

If a coin of smaller diameter than the proper denomination is inserted through the second coin chute 46 into the first coin chute 44, then it will fall behind the abutment extension 43 and thus fall into the coin return receptacle 55. With a coin 45 of the proper denomination inserted, it will remain in the first coin chute 44 as supported by .the abutment extension 43. This first coin chute 414 is defined by the abutment surfaces 41 and 43 and by the face wall 27 when the lock bolt 25 is in the first or retractedposition of FIGURE 1 The key 35 may now be rotated. clockwise to move the lever 36 clockwise whereupon an edge 64 of the, lever second end 38 will engage the coin 45. This is the position shown in FIG- UR E 2. The coin 45 thus covers the entrance to the aperture or slot 48 so that the lever 36 will not enter this slot 48. A continued clockwise rotation of the lever 36 from the position shown in FIGURE 2 to the position shown in FIGURE 3 creates a lateral thrust through the opposite faces of the coin 45 to extend the lock bolt 25 to the position shown in FIGURE 3. For this embodiment, this is an arcuate rotation from about a 30 degree position to about a 90 degree position. In this position of FIGURE 3, the lever 36 extends generally horizontally and parallel to the first path 42. The coin 45 is carried downwardly along the face wall 27 by the frictional engagement with the edge 64 ofthe lever 36. The coin 45 slides down this face wall 47 until the lower edge of the coin rests on the shelf abutment 54 as shown in FIGURE 3. In this position the coin is pinched between the lower end of the face wall 27 and an outer surface of the lever second end 38. This securely retains the coin in this position shown in FIGURE 3 since the coin is also retained between the rear wall 17 of the case12 and the front cover 22.

In this position of FIGURE 3 the locker is locked and the, key 315 may be removed .to securely check the persons articles in the locker. In this locked position of FIG- URE 3, the lever 35 is substantially horizontal and parallel to the first path 42. Accordingly, as this extended position of FIGURE 3 is approached, the lever 36 acts as toggle lever means maintaining the lock bolt 25 in the extended position and also progressively increases the leverage acting on the lock bolt as this second arcuate position of the lever 36 is approached. This toggle lever action prevents anyone tampering with the lock from retracting the lock bolt as by using the point of a knife in any opening between the door 13 and door frame 14. Additionally, the detent spring 57 retains the lever 36 in this second arcuate position.

When the locker is locked, the abutment extension 23 on the lock bolt 25 is moved to a position to close the coin receiving chute 46, so that no second coin may be inserted.

When the person returns to the locker and inserts the key 35 in the key cylinder 34, then the key may be rotated counterclockwise toward the first arcuate position shown in FIGURE 1. In so doing, the lever outer surface 65 is first moved away from the coin 45. After arcuate movement of about degrees, in this embodiment of the invention shown, the extending tongue 39' of the lever will engage the abutment 29 on the inner end of the lock bolt 25 and thus move the lock bolt to the retracted position of FIGURE 1. As this movement occurs, the face wall 27 pushes the coin 45 off the shelf abutment 5d and thus the coin falls into the coin return receptacle 55.

The fact that the coin 45 is retained between the surface 65 and the face wall 27 when the lock bolt is extended, is an anti-tampering feature. The lock bolt must be extended in the position of FIGURE 3 before the key may be withdrawn. The fact that the coin 45 is securely retained within the lock mechanism 11 at this time is assurance that a coin deposit has been made to assure safe return of the key 35. It is only when the key is returned, inserted in the key cylinder 34 and then turned to the initial position of FIGURE 1 that the coin 45 may be retrieved. In the position of FIGURE 1 the key 35 is not removable from the lock.

The second end 38 of the lever 36 is a hook end which may enter an angled slot or aperture in the lock bolt in the absence of a coin and this entrance into this aperture or slot 48 creates a condition as described above wherein in; sufficient force may be transmitted from the lever 36 to the lock bolt to extend this lock bolt. However, upon the presence of a coin in the first coin chute 44, lateral thrust may be transmitted through the opposite faces of this coin to extend the lock bolt.

The face wall 27 is transverse to the first path of movement 42 and, as shown, is preferably perpendicular to this path. It will be noted that there is no confining coin chute which confines both faces of the coin 45 in all positions of the lock bolt. The first coin chute 44 is defined on one side by the face wall 27 on the lock bolt 25 and defined on the other side by abutment surface 41 fixed on the case. Thus, there is no surface of a coin chute impeding movement of the lever second end 38. Further, it is the edge 64 of the lever 36 which engages the coin 45 to retain it in place against the face wall 27 during arcuate clockwise movement of the lever 36. As shown, the friction between edge 64 and the coin 45 is greater than the friction between coin 45 and the face wall 27, however, this may be reversed, if desired, so that the coin 45 is not moved downwardly along the face wall 27 as the lock bolt is extended.

If desired, the coin opening 56 may be omitted from the lock case 12 in which case the lock mechanism will become a coin retained mechanism rather than a coin return mechanism.

The lever second end 38 may be characterized as a thrust member movable in the case along the second path 49 to intersect the first path 42 at an acute angle. This thrust member will engage the wall means 50 and 51 of the aperture or slot 48 as thrust Wall means. These thrust wall means are disposed effectively on a line parallel to the first path 42 since it may be considered that the effective points of cont-act of surfaces 60 and 61 with the walls 50 and 51 will be on a generally horizontal line. Thus, this gives a primary component of force generally vertically downwardly to establish no movement of the lock bolt 25. It may also be considered that the edge 64 of the lever 36, as viewed in FIGURE 2, when acting through the coin 45, will establish a component of force to extend the lock bolt 25. In the absence of a coin in the first coin chute 44, the corner 62 of the lever 36 exerts a force on the lock bolt 25 which is generally vertically downwardly to prevent extension of the lock bolt 25.

FIGURE 8 shows a modification of the invention wherein a lock mechanism 71 may be generally similar to the lock mechanism 11 shown in FIGURES 17. This lock mechanism 71 may include a lock case 72 which may be smaller physically than the lock case 12. One reason for this is that a coin return receptacle 73 is formed generally exterior to the lock case 72. The lock case 72 may be made of heavy gauge sheet metal for example and the coin receptacle 73 may be formed as an extension of the bottom wall 74 of the case 72. A hook end 75 on this coin receptacle 73 retains the coin 45 when a coin falls out of a coin opening 76 in the bottom wall 74. The lock case 72 is adapted to be mounted on the inside wall of a door such as the door 13 and this would be a vertical surface retaining the coin in the coin return receptacle 73. The sheet metal part forming the coin re ceptacle 73 may be twisted or warped to aid in this retention of the coin.

The lock mechanism 71 of FIGURE 8 is shown in the partly extended position of the lock bolt: 25A which is similar to the lock bolt 25 except for a shortened face wall 27A. Because of this shortening, the coin 45 is retained in engagement with the face wall 27A throughout a majority of the arcuate clockwisemovem-ent of the lever 36 but is then released. This releasing is near the end of the degree arc of movement and the coin 45 thus drops through the opening 76 into the coin receptacle 73. The teachings of FIGURES 1 and 8 may be combined if it is desired to construct a lock mechanism having a case smaller than that shown in FIGURE 1 yet still having the coin retaining feature of FIGURE 1 when the lock bolt is extended. In this case a shelf abutment 54 might be provided in the lock case 72 with a long face wall 27 so that the coin 45 would be retained in the extended position of the lock bolt 25. Then upon return arcuate movement of the lever 36, the face wall 27 would push the coin off the shelf abutment 54 to have it drop through the coin opening 76 into the coin return receptacle 73.

Although this invention has been described in its preferred form with a certain degree of particularity, it is understood that the present disclosure of the preferred form has been made only by way of example and that numerous changes in the details of construction and the combination and arrangement of parts many be resorted to without departing from the spirit and the scope of the invention as hereinafter claimed.
